摘要:
Methods of identifying agents which alter the NAD-dependent deacetylation activity of a Sir2 protein or a fragment of a Sir2 protein are disclosed. The acetylated protein can be a nuclear protein, such as a histone protein, or a cytoplasmic protein. The Sir2 protein employed in the methods can include at least a core domain of a Sir2 protein, such as a human Sir2 protein.

This invention relates to methods of screening compounds that modulate cellular and organismal processes by modification of the activity of SIR2 and/or transcription factors, e.g., p53, particularly methods of screening for compounds that modify lifespan and/or metabolism of a cell or an organism by modulation of the activity of SIR2 and/or transcription factors, e.g., p53, and more particularly to methods of screening for compounds that modulate the activity of Sir2 and/or transcription factors, e.g., p53. In particular, the present invention relates to a method for screening a compound, by providing a test mixture comprising a transcription factor, Sir2, and a Sir2 cofactor with the compound, and evaluating an activity of a component of the test mixture in the presence of the compound. The invention further relates to therapeutic uses of said compounds. The invention further relates to a method of modifying the acetylation status of a transcription factor binding site on histone or DNA by raising local concentrations of Sir2.

摘要:
The present invention generally relates to a nicotinamide adenine dinucleotide (NAD) biosynthesis system and methods of screening for NAD biosynthesis effectors. Among the various aspects of the present invention is the provision of an in vitro-reconstituted mammalian NAD biosynthesis system that can be used for the high-throughput screening of chemical activators and inhibitors for mammalian NAD biosynthesis. Another aspect of the invention provides a method of identifying a compound that effects in vivo activity of NAD metabolic enzymes. Further aspects of the invention include nucleic acid sequences, vectors, and transformed cells that can be used in the methods described herein.
